A) cos?1 (0.547)
B) cos?1 (0.4484)
C) cos?1 (0.5)
D) cos?1 (0.3)
Correct Answer: A
Solution :
Direction of scattered photon \[\cos \varphi =1-\frac{\Delta \lambda {{m}_{e}}c}{h}\] Here \[\Delta \lambda =0.011\,\,{\AA}\] \[\therefore \,\,\cos \varphi =1-\frac{0.011\times {{10}^{-10}}\times 9.1\times {{10}^{-31}}\times 3\times {{10}^{8}}}{6.624\times {{10}^{-34}}}\] \[=1-0.453=0.547\] \[\therefore \,\,\varphi ={{\cos }^{-1}}\,(0.547)\]You need to login to perform this action.
